I heard Sufyaan [rahimahullaah] saying: It is incumbent upon you that you do not attach your heart to the worldly life [i.e. a blameworthy attachment as opposed to seeking one’s needs] and you are not eager for its attainment [i.e. the eagerness that leads to sin, transgression, greed etc], and Allaah will make you see the concealed affairs of the worldly life [i.e. its corruption, true reality, worries etc when we are attached to it in a blameworthy manner]. It is incumbent upon you to have [الورع – apprehensive fear – that type of fear that will keep you away from those affairs that are doubtful and thus may affect you in the afterlife] and Allaah will make your giving account on [the day of judgement] less burdensome. Leave what makes you doubt for that which is not doubtful; leave those affairs that resemble the truth but are falsehood in reality and your religion will be safeguarded.

[Hilyatul Awliyaa 7/20]

NB: الورع – translated as ‘Apprehensive Fear’ was taken from one of Ustaadh Amjad Rafiq’s articles
